Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] See also Figure 1-4 , an embodiment provided by the utility model.

[0020] A fixing fixture for drilling, comprising: a fixing frame 1, a base 2 is installed at the bottom of the fixing frame 1;

[0021] Also includes:

[0022] The side slots 3 are opened on both sides of the front end surface of the fixed frame 1 , and a lead screw linear module 4 is installed inside the side slots 3 . A movable frame is arranged based on a lead screw slider 7 on the lead screw linear module 4 .

[0023] A chip removal groove 15 is provided at the middle position of the upper surface of the fixed frame 1. The front end surface of the chip removal groove 15 is provided with a chip removal opening 17. An inclined guide plate 16 is provided inside the chip removal groove 15, and the lower end of the inclined guide plate 16 extends to the chip removal opening 17.

[0024] A chip collecting groove 18 is provided at the middle position of the front end surface of the base 2 and is located below the chip discharge opening 17;

[0025] By setting the side slot 3, the fixture positioning position is a side movable structure. When the workpiece is placed on the upper surface of the fixed frame 1 for drilling, the generated waste chips will not enter the movable structure, avoiding the movable structure from being affected; by setting the chip discharge groove 15, the waste chips generated during drilling will fall into the chip discharge groove 15 from the upper opening, and the waste chips will be guided to the chip discharge port 17 by the inclined guide plate 16; by setting the chip collection groove 18, the waste chips at the chip discharge port 17 will fall into the chip collection groove 18, which is convenient for users to centrally handle;

[0026] A storage container may be placed at the chip collecting groove 18 so that waste chips can directly fall into the storage container of the chip collecting groove 18 , making it convenient for users to collect them.

[0027] See also Figure 2 The clamping mechanism is set as an electric telescopic rod 11, and the electric telescopic rod 11 is set symmetrically on the left and right, and a pressing plate 12 is installed at the telescopic end of the electric telescopic rod 11;

[0028] The electric telescopic rod 11 is used to drive the pressing plate 12 to telescopically move. Through the telescopic movement, the distance between the pressing plate 12 and the workpiece is adjusted. When clamping and fixing, the electric telescopic rod 11 presses the pressing plate 12 down on the workpiece, so that the workpiece is firmly fixed on the upper surface of the fixed frame 1 by multiple pressing plates 12, thereby improving the stability and firmness during drilling;

[0029] The electric telescopic rod 11 is symmetrically arranged, and is mainly used to press the side of the workpiece, leaving the middle part empty, which is suitable for workpieces that need to be drilled in the middle, so that the waste chips generated during the drilling fall into the chip discharge groove 15 from the middle.

[0030] See also Figure 1 The screw linear module 4 includes a ball screw 5, a screw motor 6 is installed at the end of the ball screw 5, and a screw slider 7 is installed on the outer wall of the ball screw 5;

[0031] The screw motor 6 and the ball screw 5 are used to drive the screw slider 7 to move linearly. The position of the clamping mechanism is adjusted by movement, which makes it convenient to adjust the position of the positioning limit according to the size of the workpiece, thereby improving the flexibility of the clamp.

[0032] See also Figure 1 , Figure 2 A connecting member 8 is installed on the outer wall of the screw slider 7, a bracket 9 is installed above the connecting member 8, and a fixing plate 10 is located between the two brackets 9;

[0033] The connection member 8 and the bracket 9 are provided to support and reinforce the movable frame, and enable the movable frame to be connected to the lead screw slider 7 to realize the moving operation.

[0034] See also Figure 3, both sides of the outer wall of the rear end surface of the fixed frame 1 are provided with a slide groove 13, a driven slider 14 is installed inside the slide groove 13, and the bracket 9 is slidably connected with the slide groove 13 through the driven slider 14;

[0035] When the screw linear module 4 drives the movable frame to move, the bracket 9 on the other side drives the driven slider 14 to slide in the slide groove 13, so that the movement process of the fixed movable frame is smoother and more stable. The slide groove 13 is opened on the rear end surface and is not easily affected by waste chips.

[0036] See also Figure 2 , positioning holes 19 are provided at the four corners of the outer wall of the base 2;

[0037] The positioning holes 19 are used in combination with bolts to fix the base 2 on the tabletop, thereby improving the stability and firmness of the entire clamp.

[0038] When in use, the base 2 is fixed on the work surface by bolts, and the workpiece is placed on the upper surface of the fixed frame 1, so that the drilling position of the workpiece is located at the upper opening of the chip groove 15; the movable frame is driven to the desired positioning position by the lead screw linear module 4, and during the movement, the bracket 9 on the other side is driven in the slide groove 13 by the driven slider 14;

[0039] After reaching the desired positioning limit position, the electric telescopic rod 11 extends downward, driving the pressing plate 12 to contact the workpiece, and the workpiece is firmly fixed on the fixed frame 1 through the downward pressure applied by the electric telescopic rod 11;

[0040] The drilling equipment performs drilling operation on the workpiece, and the waste chips produced during drilling fall into the chip discharge groove 15, and the waste chips are guided to the chip discharge port 17 through the inclined guide plate 16, and the waste chips at the chip discharge port 17 fall into the storage container in the chip collection groove 18;

[0041] After drilling is completed, the electric telescopic rod 11 is reset and retracted upward to separate the pressure plate 12 from the workpiece, the workpiece is removed, and a new workpiece is replaced on top for a new round of drilling operation. After multiple operations, the storage container filled with waste chips in the chip collection groove 18 is removed and replaced.

[0042] The use of the present invention has the following effects:

[0043] The utility model adopts the setting of the side slot to make the positioning part of the clamp a side movable structure. When the workpiece is placed on the upper surface of the fixed frame for drilling processing, the waste chips generated will not enter the movable structure, so as to avoid the movable structure being affected; by the setting of the chip discharge groove, the waste chips generated during drilling will fall into the chip discharge groove from the upper opening, and the waste chips will be guided to the chip discharge port by the inclined guide plate; by the setting of the chip collecting groove, the waste chips at the chip discharge port will fall into the chip collecting groove, which is convenient for users to centrally process; it solves the problem that the existing drilling clamp does not have a chip discharge structure, and the waste chips generated when drilling a fixed object will be directly accumulated on the surface, and some of the waste chips are easy to enter the slide groove, which is easy to affect the normal use of the clamp and is also inconvenient for users to clean up.

[0044] The electric telescopic rod is used to drive the pressure plate to move telescopically. Through the telescopic movement, the distance between the pressure plate and the workpiece is adjusted. When clamping and fixing, the electric telescopic rod presses the pressure plate down on the workpiece, so that the workpiece is firmly fixed on the upper surface of the fixed frame by multiple pressure plates, thereby improving the stability and firmness during drilling.

[0045] The screw motor and ball screw are used to drive the screw slider to move linearly. By moving and adjusting the position of the positioning component, it is convenient to adjust the position of the positioning limit according to the size of the workpiece, thereby improving the flexibility of the fixture. When the screw linear module drives the positioning component to move, the bracket on the other side drives the driven slider to slide in the slide groove, making the movement process of the positioning component smoother and more stable. The slide groove is opened on the rear end face and is not easily affected by waste chips.

[0046] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
